Title: Magnetic disk device
Inventor: NISHIDA HIROSHI
IPC: G11B25/04
Filed: 1986-03-24
Abstract: PURPOSE:To keep uniform a temperature distribution between a disk group and a head group, and to attain a recording with high density and a few off- track quantity, by making an interval between the upper and lower bases and a magnetic disk larger at a side on which a motor is provided. CONSTITUTION:Five sheets of disks 1-5 supported with a shaft 8 are driven by a rotor magnet 13 and a stator 14, and a servo head 16 and seven data read/write magnetic heads 17 are fixed at a carriage 21 through a head arm 18. The carriage 21 is guided by a rail 20 and a bearing 19, and is driven by a linear motor 22. An interval 11 between a lower part base 7 and the disk 5 is constituted larger than an interval 10 between an upper base 6 and the disk 1 because heat is generated by the magnet 13 and the stator 14. Therefore, it is possible to keep the temperature distribution between the plural disks and the head uniformly without increasing the number of the disks, and the recording with a few off-track quantity and high density can be obtained.

Abstract: PURPOSE: To surely prevent the occurrence of water hammer by a simple structure easy in installation by interposing a valve means in the connecting pipe, which provides different flow resistance depending on the flow direction, in the pipe conduit water hammer prevention device equipped with a connecting pipe to be connected to a main pipe conduit, and with an air valve formed at its apex section. CONSTITUTION: This invention is concerned with the pipe conduit water hammer prevention device which is connected to a main pipe conduit 3 for transporting fluid, and is equipped with a connecting pipe 10 extended upward, and with an air valve formed at the apex of the connecting pipe 10, and a valve means 50 which provides different flow resistance depending on the flow direction, is interposed in the connecting pipe 10.  In this case, when fluid columns within the main pipe conduit 3, which have lost their inertia, and separated, reversely flow so as to be recombined with each other, the speed of air exhausted out of the main pipe conduit 3 is extremely low, furthermore, air staying in the main pipe conduit 3 acts as a cushion member, and abrupt increase in pressure, which is produced when the once separated fluid columns are recombined with each other by reverse flow, can be positively prevented. Thus as mentioned above, the occurrence of water hammer can be surely prevented by a simple structure easy in installation.

Abstract: PURPOSE:To prevent saturation of a magnetic flux, to prevent incurring of a magnetic flux loss, to improve efficiency, and to simplify structure by integrally molding a yoke to perform attraction for punching in a manner that the sectional area of a magnetic flux passage is uniformized. CONSTITUTION:A punching device 1 is provided with a punch pin 2 for punching a card C, a moving body 3, a yoke 4 to attract the moving body 3, and a spring 5 through the force of which the moving body 3 is energized in a direction opposite to a punching direction. A coil 8 is attached in a ring groove 43 of the yoke 4, and through excitation of the coil, the moving body 3 is attracted. In the yoke 4, the thickness of a ring part 42 near the center thereof is increased and that of an outer peripheral part 44 is decreased. Thereby, the ring part 42 and the outer peripheral part 44 are equalized in a magnetic flux passage sectional area, and thus a magnetic flux is prevented from saturation throughout the whole of a passage to ensure an excellent flow. Further, since the yoke 4 is integrally molded by press molding, no gap is provided, resulting in prevention of incurring of a magnetic flux loss and improvement of assembly properties.

Abstract: PURPOSE:To adjust properly pressure of an extruder and to improve the mixing effect by setting up ring valves in two-stages which choke a clearance formed in the longitudinal direction and in the radial direction between a screw and a cylinder. CONSTITUTION:Connecting the clearance delta1 and delta2 in the radial direction of the ring valves 401 and 402, the delta1 on the upstream side is made bigger than the delta2 on the downstream side. The ring valve 401 on the upstream side is made to proceed by shifting the position of the choke starting point when the screw 31 is moved in the downstream direction (an arrow A). That is, a clear ance H1 a clearance H2 is formed. When the ring valve 401 of the bigger clerance delta1 on the upstream side is choked and the screw 31 is further moved, the ring valve 402 of the smaller clearance delta2 on the downstream side is choked. The respective points which can be applied to each resin ranging from the high-viscosity one to low-viscosity one can be thereby found.

Abstract: PURPOSE:To make measuring pressure easily adjustable by making it possible to adjust the length of a spring that energizes the spindle of an inside diameter measuring machine. CONSTITUTION:When a pair of levers 18 turnable around a shaft 19 are gripped, a pressing member 21 forces a contact member 5 upward against a spring 6 and the spindle 4 fixed to the member 5 ascends simultaneously and therefore a measuring contactor 25 retracts into a cylindrical body 3 while lifting an operating body via tapered surfaces 25B, 23A by means of a spring 27. When the levers are released, the measuring contactor is pressed to the inside wall 30A of the hole by the motion reverse from the above. When an operating member 9 is turned, the member 8 engaged with the spiral groove 9A on the inside surface of said member 9 moves upward and downward along the long hole guide groove 2C of a cylindrical body 2 and therefore a moving member 7 moves as well, thereby adjusting the force of the spring 6. On the other hand, the displacement of a measuring shaft 5B is read with a dial gage 15.
